Gharials are critically endangered crocodilians with specialised ecological needs, facing extinction from river degradation, fishing nets, and sand mining.
Gharials caught in fishing nets experience drowning distress as obligate air-breathers unable to surface. Sand mining destroys nesting beaches, preventing reproduction and causing nest abandonment. Gharials have poor thermoregulatory capacity compared to other crocodilians, making habitat degradation that removes basking sites a welfare concern. Conservation breeding programmes have good captive welfare but released animals face a highly degraded natural environment.
